constexpr V base() const& requires std::copy_constructible<V>; | (1) | (since C++23)
constexpr V base() &&; | (2) | (since C++23)

Returns a copy of the underlying view `base_`.

1) Copy constructs the result from the underlying view. Equivalent to: return`` `base_`;
2) Move constructs the result from the underlying view. Equivalent to: return std::`move`(`base_`);

### Parameters

(none)

### Return value

A copy of the underlying view.

### Example

Run this code

    #include <algorithm>
    #include <functional>
    #include <ranges>

    int main()
    {
        static constexpr auto v = {1, 1, 2, 2, 3, 3, 3};
        constexpr auto chunks = v | std::views::chunk_by(std::equal_to{});
        static_assert(std::ranges::equal(v, chunks.base()));
    }
